improve architecture: externalize account from strategy

[amor71]

Is your feature request related to a problem? Please describe.
Currently, the account_id is handled within the strategy. This means that certain checks, such as if enough balance exists for trade, can only be done internally per strategy. Need to improve architecture and move this to the framework.

Describe the solution you'd like
change architecture a big, make account-id mandatory, expose externally, and have the framework handle checks & transactions.
